" Application filed September 22, 1927. Serial No. 221,241. I

which fuel is converted from the liquid phase to the vapor phase before itenters the burner. In such stoves a heat responsive vaporizer,

commonly called a generator, communicates with a tankcontaining liquid fuel under pressure. My invention has to do particularly with providing a unit consisting of the tank andv vaporizer so constructed and so co-lined with the stove casing that it may be i conveniently applied to the stove casing to aline the generator with the burner inlet and be easily removable so that the tank can be filled with liquid fuel independent of the casing. According to my invention, the entire unit can'be introduced laterally into the casing, preferablythrough the front so' that'the unit will be visible when in place, thus making it possible to examine the valves, gage, etc., without removing the unit from and unit, I have found it expedient to make certain improvements in the general con;

struction of the stove, all of which will be: specifically referred 'to hereinafter, reference being had to the accompanying drawings in Y which p Fig. 1 is a front view of a stove constructed in accordance withmy invention. v Fig. 2 is a cross-sectionalview through casing, showing the tank in place.

F ig; 3 is an end view of the stove.

the

Fig. 4 is'a horizontal section through the";

radiant heaters, the unit being shown in elevation with the door swung to open position. 3 Fig. 5 is a perspective view of the removableunit and I Fig. 6'is anjenlarged viewof the upper part of the casing, showing how the units are attached .and'how .the upper portion of the stove isconstructed.

The casing is'illustrated as'having an open front. It consists of a back 1 with'two sides 2 and 8' diverging toward the front and a bottom 4. The two sides are held against spreading at the forward portion by a tierod 5 which serves as' a hinge for the front door 6, which closes the unit containingchamber 7. The door or closure may, if de-' sired, be apart ofthe unit. That'is, the door may-.be fastened to the unit so that it will come away from the stove when the unit is removed. The'edges of the door are shown as adapted to engage the spring frictionlatches 8 in the sides 2 and 3 of the casing of the handle, rest on the'fioor and form a supportrfor the doora When the door is closed, the bars lie close against the door, as clearly seen 1n Figures J and 2. In the upper part. of the casing is a burner casting 12 which extends from end to end of the casing and whlch is secured to the casing The burner per se is not new, so any suitable burner form maybe employed. The-burner casting has an ofleset mixing chamber 13'witha vapor inlet 14 at one end so that vapor from the generator, to be hereinafter referredto, may enter the mixing chamber, the velocity of the vapor=drawing air into themixing chamber .as is common with such burners. The mixing chamber communicates with a vapor space 15 in the burner casting in rear of the mixing chamber and at the top. of the casting areburners 16, the casting being trough-shaped at its'upper portion to receive the radiants 17 of suitable refractory material. The radiportions 23 and 24 to form a reflector, a cat insulator and to enhance the appearance of the stove. The sheet 21 is preferably constructed of some bright metal to enhance the appearance of the stove. An overhanging top sheet 25 is secured to the back sheet and to the sides 2 and 3 and at its front edge,-it

is provided with a curved bead 26 and secured at its edges by two strips 2.7.and 28 which extend down-to the front edgesof the sides.

2 and 3. The casting 12 is provided with two outstanding hooked-shaped supports 29 and 80 to which the removable unit may be attached-when it is in functional position.

The removable unit is shown as consisting of a tank 31, having a normally closed filler opening 32"anda pressure gage 33 ofapintroducing the air. An outlet connection .proved construction tm show the pressure in i thetank. A built-in pump 34is indicated in 35 is provided for the tank 31, having a valve 36 therein which controls the flow of .fuel from the tank, A pipe 37 leadsfrom the connection 35 to a preheater 38 consist-ing of a hood 39 with an air hole 40 in one side, the hood having a return bend discharging into a priming cup 41 beneath the vaporizer of generator 42. The vaporizer or generator is fastened to an upstanding brace 43, in the form of a bracket, through which the vaporizer or generator 42 passes and it carries a clamp 44 which clamps the nipple 45 rigid with the generator so that the generator is held in place. The nipple communicates .with the connection 35 through apipe 46 and when the valve-36 is opened, passage of fluid through the generator 42 will be controlled by the needle valve 47 in a well understood manner. At the end opposite the bracket member 43 is a bracket member or hanger 48,

having an off-set portion 49 with an opening ally alined and supported by the lugs 29 and 30 or by the burner at the vapor inlet, the principle remains the same.- The brackets 43 and 48 support a drip-pan which extends the length of the tank 31 and which supports the preheater 38 and the support. 54 for the discharge end of the generator 42. Therefore, when the unit is in place, the front end of the generator 42 will aline with the vapor inlet opening 14, of the mixing chamber 13, of the burner casting 12.

To ignite the burner of the stove, the valve 36 should .be turned about one turn to the left. Then the flame from one or two lighted matches, held in the left hand, can be ap plied to the pipe 37 just over the cup 41.

When the matches have about been consumed, the operator may open the valve 55 with the right hand, igniting the fuel at the. preheater so that a hot blast will be impinged upon the generator 42. It is recommended I that the hot blast be permitted to impinge the generator 42 for about one and a half minutes. The main fuel or needle valve 47 may then be opened. The fuel may now be ignited at the radiants. When the radiants are lighted, the valve 55 may be closed and since the burner casting 12 is provided'with burners 56, in rear of the generator 42,. the genera-tor 42 will be maintained at a temperature sufficiently high to vaporize the incoming fuel and since the valve 47 will con-' trol the amount of fuel passing into the burner casting, the amount of heat generated by the stove can be regulated. The casing may be provided with a handle or bail 57 and an appropriate guard 58 above the door 6 and in front of the radiants..

The end 3 of the casing is provided with two holes 59 and 60 so. that access to the pump 34 and to the valve 47 may be had when the unit is in operative position within the casing.

In order to remove the tank to fill it, it will be necessary only to close all the valves and unhook the brackets 43 and 48 from the supporting means shown as lugs 29 and 30.

By introducing the removable unit'from the front instead of through the end of the casing, the front of the stove will always be unobstructed. There is a material advantage in this because suchstoves'are often put in fireplaces, so if the unit had to be removed from the end, the whole casing would of necessity have to be removed to operate the gen erator valve, etc. whereas with my invention the valve and pump can be operated without disturbing the casing.
